ERASTUS S. STAHLEY, OF AURORA, NEBRASKA.

WINDMILL.

SPECIFICATION formingpart of Letters Patent No. 223,256, dated January6, 1880.

Application filed July 21, 1879.

To all whom it may concern Be it known that I, ERASTUS S. SIAHLEY, ofAurora, in the county of Hamilton and State of Nebraska, have inventedcertain new and useful Improvements in Windmills; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanyingdrawings, which form a part of this specification, and inWhich Figure 1 is a side elevation. Fig. 2 is a vertical axial sectiontaken on line mm, Fig. 1. Fig. 3 is a horizontal section taken on line y3 Fig. 1; and Fig. 4 is a view of the under side of the cam operatingthe bell-crank and pump rod.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to horizontal windmills, or that class ofwindmills in which an exterior series of vertical gates or shutters maybe adjusted to admit more or less wind to a horizontal wheel within; andit consists in the detailed construction and combination of parts,substantially as hereinafter more fully described.

In the drawings, A A are the posts or uprights, supporting a platform,-B, and roof 0. D are the gates or shutters, which are pivoted in theroof 0 and platform B, and operated by rods d, which connect with acircular disk, E, having a lever-handle, 0, upon its under side, in likemanner as the gates of a water-wheel. Disk E consists of two parts orsections, its lower part, 6, being sunk into a circular opening in theplatform B, as shown in Fig. 2, the shaft or vertical axle F passingthrough an opening in disk E e.

The wind-wheel consists of an upper and lower annular plate or frame, g9-, between which the vertical fans Gr are secured. Shaft F passescentrally through disks 9 g, its pro- 5 jecting upper end being pivotedin the roof,

and its lower end is journaled in a cross-piece, a, below the platformB.

H is a cam keyed eccentrically upon shaft F, and having a groove, h, onits under side.

I is a bell-crank, journaled in bearings it, that project from thecrosspiece a under cam H, into the groove h of which the end of itsupper arm is fitted, which is provided with a frictionroller, so as torun easy in the groove when the shaft revolves. To the end of the otherhorizontal arm of bell-crank I is pivoted the pump or sucker rod K,which reaches down into the well.

By turning lever e the gates may beadjusted to admit more or less windto the wheel; or they may be closed altogether when it is not desired tooperate the mill.

The annular step e of the. plate E, upon which the rods (1 d arepivoted, being inserted and fitted into the circular opening in theplatform 13, prevents lateral play or oscillation of said plate or diskE, and of the rods and shutters connected thereto, while at the sametime the plat-form B forms a bearing or support for the stepped disk E.

By the combination and arrangement of the grooved cam H and bell-crankI, as described, there is a minimum of friction, which insures certaintyof operation of the mill even in a light wind and under circumstanceswhen an ordinary mill would be unable to perform its worksatisfactorily.

Having thus described my improvement, I claim and desire to secure byLetters Patent of the United Sta-tes- In a windmill of the describedclass, the combination of the circularly-perforated platform B,supported upon standards A A, circular disk E, having annulardownward-projecting step or shoulder c, fitting into the circularopening in platform B and provided with the leverc, and pivoted gates orshutters D, provided with the operatingrods d, substantially as and forthe purpose herein shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

ERASTUS SETH STAHLEY.
